side, above the saltest water (36.5°/,.), as just noted. 
Apart from a possible salt tongue in the center of the channel, the 
salinity curves as a whole dip from north to south, and it is worth

Fia. 26.—Temperature sections on the Gun Cay-Cape Florida line; stations 10202, 10203, 10204. 
Between Cape Florida and Gun Cay the channel is only about 900 
meters deep and 60 miles wide. Nevertheless, we find as great a 
range of salinity (fig. 27) and almost as great a range of temperature 
(fig. 26) as in the Key West-Habana profile. As before, the water 
-was coldest and freshest next to Florida, warmest and saltest off 
the Bahama Bank; and the two eastern stations are saltest (36.5°/,.)
